Abstract
This work is part of the valorization of spontaneous medicinal plants, a large part of which is still virgin and
requires in-depth studies, and then our objective will be an extraction of the essential oils of the aerial part
and the flowers of Cotula cineria, identifying physical parameters, pH measurement, density measurement,
and refractive index. In parallel, biological activity (Antioxidant) is studied. Regarding the physical
properties, we find the essential oils of the flowers and the aerial part have basic characters with the values of
pH 8,39 and 8,60, the density is 0.95 and 0.90 and the index of refraction is 1,33350 and 1,33375
respectively. Both antioxidant activities show that both essential oils have IC50 45.98mg/ml and 79.28mg/ml
for the flowers and the aerial part of Cotula cinerea respectively. A large ability to trap the DPPH radical is
noted with the value of IC50 0.04% for ascorbic acid.
